C# Class Accord.Fuzzy.FuzzyOutput

The class represents the output of a Fuzzy Inference System.

The class keeps set of rule's output - pairs with the output fuzzy label and the rule's firing strength.

Sample usage:

// linguistic labels (fuzzy sets) that compose the distances FuzzySet fsNear = new FuzzySet( "Near", new TrapezoidalFunction( 15, 50, TrapezoidalFunction.EdgeType.Right ) ); FuzzySet fsMedium = new FuzzySet( "Medium", new TrapezoidalFunction( 15, 50, 60, 100 ) ); FuzzySet fsFar = new FuzzySet( "Far", new TrapezoidalFunction( 60, 100, TrapezoidalFunction.EdgeType.Left ) ); // front distance (input) LinguisticVariable lvFront = new LinguisticVariable( "FrontalDistance", 0, 120 ); lvFront.AddLabel( fsNear ); lvFront.AddLabel( fsMedium ); lvFront.AddLabel( fsFar ); // linguistic labels (fuzzy sets) that compose the angle FuzzySet fsZero = new FuzzySet( "Zero", new TrapezoidalFunction( -10, 5, 5, 10 ) ); FuzzySet fsLP = new FuzzySet( "LittlePositive", new TrapezoidalFunction( 5, 10, 20, 25 ) ); FuzzySet fsP = new FuzzySet( "Positive", new TrapezoidalFunction( 20, 25, 35, 40 ) ); FuzzySet fsVP = new FuzzySet( "VeryPositive", new TrapezoidalFunction( 35, 40, TrapezoidalFunction.EdgeType.Left ) ); // angle LinguisticVariable lvAngle = new LinguisticVariable( "Angle", -10, 50 ); lvAngle.AddLabel( fsZero ); lvAngle.AddLabel( fsLP ); lvAngle.AddLabel( fsP ); lvAngle.AddLabel( fsVP ); // the database Database fuzzyDB = new Database( ); fuzzyDB.AddVariable( lvFront ); fuzzyDB.AddVariable( lvAngle ); // creating the inference system InferenceSystem IS = new InferenceSystem( fuzzyDB, new CentroidDefuzzifier( 1000 ) ); // going straight IS.NewRule( "Rule 1", "IF FrontalDistance IS Far THEN Angle IS Zero" ); // turning left IS.NewRule( "Rule 2", "IF FrontalDistance IS Near THEN Angle IS Positive" ); ... // inference section // setting inputs IS.SetInput( "FrontalDistance", 20 ); // getting outputs try { FuzzyOutput fuzzyOutput = IS.ExecuteInference ( "Angle" ); // showing the fuzzy output foreach ( FuzzyOutput.OutputConstraint oc in fuzzyOutput.OutputList ) { Console.WriteLine( oc.Label + " - " + oc.FiringStrength.ToString( ) ); } } catch ( Exception ) { ... }
